To @Z whom, tm/Cty concern:

Be it known that I, JOHN C. FORSTER, a' citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certainnew and useful Improvements in Gas-Stoves, of which the followingis a specification, reference befv ing had therein to the accompanying drawings.

The object of this `invention is to provide a compact gas-stove of sim-ple and inexpensive construction having large heating, gen? erating, and radiating capacity.

In the accompanying drawings, Figurel is a front elevation of a base-burner stoveembodying my improvements, and Fig. 2 is a vertical sectional view on line2 2 of Fig.` 1. Figs. 3 and 4 are sectional plan views taken on lines 3 3 and 4 4, respectively, of Fig. 2. Fig. 5 is a `front elevation of a surface-burner stove constructed in accordance with my invention. Figs. 6 and 7 are sectional views taken on lines 6 6 and 7 7, respectively,'of Fig. 5.

Referring to the drawings, and particularly to Figs. 1, 2, and 3, illustrating the baseburner type of stove, 2 4indicates the stovebase, and 3 the upright vertically-corrugated lire-board, provided with the usual asbestos covering 4. Behind the ire-boardis the perfor-ated heat-radiating chamber 5, of which the tire-board constitutes the front wall. neath the fire-board is the horizontally-elongated base-burner 6, provided with the usual gas connection 7 and mixer 8. The gas-emitting perforations 9 inthe top surface of the burner are arranged in a winding or serpentine line to conform to the shape of the fireboard, thus causing the latter, or rather the lower portion thereof, to be completely covered by the upwardly-burning jets of flame. Thus a compact burner of large capacity is provided and with it an equally compact tireboard,V which diffuses orradiates the heat in a most economic and eifective manner.

In applying my improved fire board to stoves of the surface-burner type (illustrated in Figs.5, 6, and 7) agas-chamber 10 is formed by wall or partition l1 immediately at the 5o rear of the vertically-corrugated fire-board,

combustion to flue connection 15.

' and the latter-constitutingthe front wall of said chamber, is suitably perforatedat 12 for the emission of gas,which`discharges uniformly through'all portions of the verticallycorrugatedV surface, 'so that the spread of iiameis even over all portions of the lireboard and is in nowise interrupted by the irregularV surface of the latter.

While in the preferredlembodiments of the invention the fire-boards are for-med of corrugated sheet or plate metal, `it will be understood that it embraces all forms of fire- 4boards of whatever material having irregular areas, whereby large amounts of heat may be generated and eifectuall y radiated in heatproducers of very compact construction.

My improved drum-like top or upper struca ture 13 is applicable alike to the base and surface-burner types, being arranged immediately above the lire-board and forming top of rear chamber 5. Formed in this top is the winding horizontally-elongated duct 14,

4open immediately over the outer surface of the fire-board, for conducting the products of From its lower end said duct extends rearward, then forward, and again rearward, inclosing the two horizontal air-heating passages 16, which open through the ends of the drum-like upper structure, whereby the heat from the said products is thoroughly radiated. To facilitate circulation, a Lhimble 17 may extend downwardlyiiiom the top surface to the upper passage 16. In the rear portion of duct 14 an elongated vertical defleetor 18 is arranged in front of 'flue 14, open only at the ends at 19, whereby the passage of the products of combustion is made still more circuitous or indirect,and thereby augmenting the volume of heat radiated by the drum-like upper structure. i

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a gas-stove, a fire-board having a vertieally-corru gated lire-surface, and a gas connection having gasemitting openings arranged complementary to the said corrugated lire-surface.
